more egr problems ( block off plate fail--- VIDEO ---)

not to be an ass but... you don't know.
Diagnostics IS scientific work. You ultimately cannot rely on anything you have not directly measured or proven. So you always start with the general concepts and work your way down to more complicated theories as you prove/disprove elements. The moment you assume something is the second you fuck yourself. Just do the logical tests and chase the clues. Ask questions when you don't understand the results. (I've been an tech for 5 years and I learn stuff everyday.)

i haven't assumed anything , i do ask questions and i do test before making conclusions
-i ran a compression test for the fun of it,
-found out #2 was below approved results/ numbers, that's fact i do have a leak in that chamber at combustion point
-poured a teaspoon of oil on the piston rings to see if it seals any fried rings on the piston, results hardly changed and i still have a lower compression than the others significantly.
-it could only mean that i am likely escaping air at the head gasket or the valves, either way the head would have to come off.
- i am not going to stop there, i am going to do a leak down test since i have access to a air compressor and other tools, and i know the usual "hear the leak " test
- bubbles in coolant in radiator = head gasket bad
- hissing noises in the exhast end = bent/bad exhast valve
- hissing noise from intake = bad/bent intake valve
- noises from oil dipstick (or vc lid) = fried piston rings

i thought were on the same page here, i don't know any other way to run this type of diagnostics, if you do Then you can "point me out" cause like you said , you have experience on hand here + five years under your belt -just don't tell me to do something that i was already going to do then say that "i dont know " b/c so far i think i have done the right things so far, but please correct me , tell me another way that can give me full proof answer other than what i plan to do .
i think i am on the right track,

i went from egr cleaning> block off plate > oil in tubes from the VC bolts that snapped loosening tube seals, i replace them but disregard the oil already in tubes which was the bogging issues i had originally , i asked and got answers , all of this progressions i made were off other answers until i discovered the problem.
the compression test is completely irrelevant.

i not trying to be a dick either, but i felt offended so I'm being defensive
